using the "redirect" function. In this case,
frequencies above 85 Hz in the LFE signal
are redirected to the center channel output to
be reproduced by the center channel moni-
tor. The sensitivity of the LFE channel can
easily be set to 0 or +10 dB according to the
monitoring needs.
To provide a flat bass response in many
different acoustic environments, a ‘bass roll-
off’ switch is included, which makes adjust-
ments to the subwoofer response in three
2 dB steps possible. Two phase alignment
switches in the crossover allow compensa-
tion for the phase delay which occurs if the
subwoofer is placed away from the main
speakers or for other phase changes in the
loudspeaker system. Four settings are pro-
vided between 0° and -270°.
